VALVE ATTACHMENT FOR FOUNTAlN-PENS.

Specification of Letters Patent.

Patented Sept. 1 1, 1906.

Application filed December 21,1905. Serial N0. 292,711.

To all whom it may-concern.-

Be it known that I, FERNAN O. CoNrLL, a citizen of Cuba, and a residentof the city of New York, borough of Manhattan, in the county and Stateof New York, have invented a new'and Improved Valve Attachment forFountain-Pens, of which the following is a full, clear, and exactdescription.

My invention relates to a device for attachment to an ordinary or anykind of a fountain-pen to regulate the flowof ink from the reservoir tothe pen proper and to entirely shut off the flow when desired.

The principal object of the invention is to provide a device of thischaracter which will be very simple in construction, easily manipulated,which can be applied to ordinary pens without changing any of theirexisting parts, and which can be removed from them to premit the pen tobe put together without the valve and not necessitate the use of anyadditional parts or the modification of the ex isting parts of the pen.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of a fountain-pen, partly in longitudinalcentral section, showing a preferred form of my improvement appliedthereto; and Figs. 2 and 3 are sectional views on the lines 2 2 and 3 3,respectively, looking in the direction of the two arrows.

I apply my improvement to any form of pen having a reservoir a and apen-holding por tion I). Ordinarily these two parts are provided withcomplementary screw-threads a/ and b, so that they may be connectedtogether. My valve comprises two elements 0 and d, the elements beingprovided with screw-threads c and (1, respectively, which are. adaptedto engage the screw-threads a and b, respectively, without in any wayaltering the ordinary parts of the penholder. It will be seen that fromthis construction the reservoir and pen-holding portion of the pen canbe separated and my improvement inserted with very little trouble andwithout any modification of the existing parts. Also it will be seenthat when a pen is originally manufactured with this device applied thedevice can be removed from the pen and the pen again put togetherwithout any modification. The parts 0 and d are provided withperforations c and (1 which are adapted to register with each other whenthe parts are turned to their proper position. They are also providedwith a pin 6, by which they are swiveled together, so that they can turnon this pin as an axis, and they have a complementary groove 0 anda-projection (1 which are preferably circular in form and fit each otherto afford a guide for turning the parts.

A stop-pin c is applied to one of the parts and a slot 7)" to the otherfor receiving it.

The operation and advantages of this device will bereadily obvious fromthe above description.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A fountain-pen having a reservoir, a pen-holdingpart, and a valve comprising two valve elements swiveled together, eachbeing removably mounted on the pen proper,

one being removably connected with the reservoir of the pen and theother removably connected with the pen-holding part thereof, the end ofthe element connected with the reservoir being a counterpart of the endof the pen-holding part of the device, and the end of the other elementbeing a counterpar of the end of the reservoir.

2. A fountain-pen having a reservoir, a pen-holding part, and a valvecomprising two valve elements swiveled together, each being removablymounted on the pen proper,

and means for removably connecting one of said elements with thereservoir and the other with the pen-holding part of the device, thepart of the reservoir connected with one element fitting the part of theholder connected with the other element whereby the valve can be appliedto or removed from an ordinary pen between the reservoir and holderwithout altering the construction of the rest of the holder.

3. A fountain-pen having a reservoir, a pen-holding part and a'valve,the valve being removably connected with the reservoir of the pen andwith the pen-holding part therename to this specification in thepresence of of, the end of the valve connected with the k twosubscribing Witnesses.

reservoir being the counterpart of the end of FERNAN O. CONILL. thepen-holding portion of the device, and Witnesses:

the other end of the valve being the counter- J osr': F. ToRAYA,

part of the end of the reservoir. 1 J ERALD A. SPRINGER.
